I’ve been doing resin for about a year now and though it took some trial and error I think I’m finally starting to get the hang of it! However there’s one problem I keep having that I’m not quite understanding. When I put a card or a sticker in a coaster or any kind of mold, it always ends up trying to rise up to the surface during the cure time, so they always end up bowing kinda funky and not looking super great. Is that happening because of how I’m pouring the resin? I put a small amount down first, then lay the card/sticker on top of it and then pour the rest of the resin in.
